In this lesson, students will discover the basics of the methane-based chemosynthetic processes and learn how organisms in cold seep communities obtain energy from methane. As they proceed, they should be able to define the process of chemosynthesis, and contrast this process with photosynthesis. Students will also explain the process of methane-based chemosynthesis and explain the relevance of chemosynthesis to biological communities in the vicinity of cold seeps.
